i put a stock trd exhaust on my scion tc. it's so sick guys it's hella loud so wherever i go people look at me and give me attention lol. basically i just want to know if you prefer your scion loud or quiet? for me, the louder the better!!!! i also put in a sick bass (one twelve, got it for 700 bucks) and i play it really loud when im in traffic so people notice me in my car lol
